To mit seltene to may concern.-

Be it lrnown'that I, ROBERT G. PET-WAY, a itizen of the United States, residing at Nashville, in the county of Davidsonand State of Tennessee, have invented certain. new and useful improvements in Roller-Bearings' for lBicycles and. other Wheeledehieles; and'I do'herehy declare the following A'to be a full,

clear,-and ,exact description 'di the invention, sguchas wiilenable' others skilled in the art to which it appertains to make and use the same.

This invention r'elates to' antifriction-bearings desigignedl generally for use on vehiclesandspeciiicaliy for use on bicycles and other footipropelled vehicle l The primary object 'of the invention is to reduce friction to a' minimum' andprovide a simple and cheap construction ofl roller-bearing the'several Yparte of which may be readily disassociated and reassembled, thus adapting the same to easy repair and cleansing.

Other objects' and advantages of the inventlon will appear in the course of the subjoined description The invention consists in' certain `novel feashowing the improved bearing constructed in accordance with this invention. Figi. 2 is a side viewof l'the 'bearing with the adjacent inf closing cap removed. Fig. 3 is an inside face view of the cap.

Similar letters of reference designate corresponding 'parts in the several figures of the drawings.

' Referring to the drawings, .A designates f. n

axle which is ordinarilylstationary, the drawings illustrating a construction' particularly desied for use in connection with thewheels of bicycles. The axle A has its ends reduced and threaded, as at a, to receive two sets of cones B, one set being employed. at each end of the axle and each set comprising two cones which are dis used reversely to each other, so as to leave a -shaped channel in which the antiiriction-rollers travel.

e hub C surrounds the axle A and is provided at its erids with flanges having rims'on sans ng. ceases. un anni.;

l the outer surfaces ofiwhich are sprocketteeth F to receive suitable' drive-chains. Between said flanges and -extending around the hub @are spokereceiving fianges, which are pref'- .erably secured-'rigidlyfeither to the hub C or to thedanges'at the end thereof or to both. D represents a series of stud=aigles the inner ends of which a, rese'cured in the hub-Harige and the enter ends .of which extend through- 'a cap-H, Upon each axle D ismounted a pairof 'cones D', disposed'reversely to each other, upon which travel series of antifri@ tion-balls d, said balls also traveling within the channeled center of a series of antiriction-rollers or wheels E, which in turn travel around the cones B.

' The caps H are provided with central open-- ings to receive the reduced ends a of the axle and are sc'iired in'place by nuts on theend lof saidA axle. `Other nuts J are placed upon the projecting ends of the stud-axles Dftlius assisting in securing the capsl-I in place and also'servingto steady the vmovable parts of 'the bearing. Each 'cap 'H is provided with a.

peripheral inwardly-extending iange which rim..

From theV foregoing description it will be seen that the cones 'may be adjusted with relation to each other for taking up wear in the bearing. Should wear take place between th'e rollers E and cones B, the cones B may be adjusted to compensate therefor.- Should wear take place between the antfriction-balls and the rollers, the smaller cones may be adjusted lso 'as to compensate therefor. The 'small cones D may be rendered adjustable by threading them upon the studaxles simibears against the inner surface of thetcothed l larly to the larger cones B. It will also lbe observed vthat the axles D are supported atv vboth ends, and the strain and Weight thereon are thus eqnalized, causing the balls and rollers to Wear evenly at all points.

While the improved bearing is described and illustrated with especial reference to bicycle-wheels, it is.to be distinctly understood that the invention is not t-be limited to such use, as the improvements are 'equally applicable to vehicle-wheel hubs and axles and at various other points where itis desired to reduce friction to a minimum. The construction is itself susceptible to changes in form IOC proportion, and minor details, which may aecordmgly be resorted torwithont departing fromjtho principle or sacrificing any ottlie lmlva'ntages of the invention.

A -ing around in contact with the cones on the said eon's, andcaps itted to the .rims and-f1 4adapted to reeeiMe and aid in snppmfting said main axle, substantially as described.

2. In an antif rietion-bearing, an axle, set-s of cones thereon, one of each set .bei-ng adt jnstable, in combination Willi a liu-b, flanges thereon, a rim at the periphery of each flange,

stndfaxles connected to said flanges, rollers thereon and traveling around in eontactn'ith stud-axles, substantiallyas described.

3. in anV antifrictionbearing, an axle. and

cones thereon, in combination with a' 1mb,

^ flanges thereon and detachable caps forming- 'inner and outer Walls, stud-axles supported in saidavalls, and .antifrici,ion-rollers on said Astud-aides and travelngaronnd in Contact with the cones on the main axle, substantially v as described,

4. In an antifricti n-bearing, an axle, and

con es thereon, in combination with a hub, ri gidly-attached flanges thereon, a r1 ni at the periphery of each'flangestndaxles projecting from said 'langes, antifriction-rollers on4 said axles and traveling around in contact with saidcones, caps'fitted to said 'flanges and having yopenings to receive said stud-` axles, and securing means for holding said caps in plaee, substantially as described.

In. testimony whereof l have, signed this specification in the nreseneeofl two subscribing \\'itnesses. y
